The app allows users to view a host’s computer desktop (presentations, documents, spreadsheets, images, etc.). I tried it out and it works really well with only a little lag, just like the regular desktop version of join.me. To join a meeting, you need to enter the meeting code sent to you by a host (note: the app can only view meetings, not host them). Obviously, the limited size of the iPhone’s display in comparison to a regular monitor means that to get a crystal clear view of an area of interest, you’ll need to pan and zoom around the screen; the regular drag-to-pan and pinch-to-zoom gestures work just as you’d expect them to, and you can also view the screen in landscape or portrait mode. The chat window can be brought up by tapping on the screen.

Although I’m not convinced it’s the kind of app I’d need very often, as my screen sharing sessions usually occur when I’m at my desk, I think it’s one of those apps that I’ll keep installed on my phone, just in case I ever need to work on a presentation or other document with someone else while I’m on the go.
